Turbo, Jeffs you guys are on point, I took some time last night and took the lid off the amp and gave things a look, went ahead and reflowed the both C1 and bingo the intermittent channel came back to life and both seem to be working great now. This was just on the bench, so now next step is to hook it all up and give it a listen. I haven't listened to this gear in 8-10 years so needless to say I am excited to have it working again. Step 1 was to get it operational and now I can start the mod program on both units. Thanks again for your help, loving it here already
